SAN ANTONIO -- A teacher was arrested and accused of having drugs in her bag at Lanier High School Monday, according to an arrest warrant.
San Antonio Independent School District police arrested Ana Carrera, 23, around 9:30 a.m. Monday, according to a spokesperson with the district.
A random drug search was taking place at the school when a drug-sniffing dog was reportedly led to Carrera's backpack.
Less than two ounces of marijuana were found, and SAISD said she was charged with a 'Class A' misdemeanor.
Carrera reportedly faces a strict penalty because drugs were found in a "drug free zone."
She resigned from her teaching position after the incident.
"This is a very disappointing incident, and we do not want it to take away from the rest of the faculty, who serve as positive role models for the students of Lanier High School," SAISD said in a statement.
This was Carrera's first year teaching at Lanier, according to the school district.
